IMPROVEMENT IN HOSE-NOZZLES.

S ecification forming part of Letters Patent No'. 187,635, datedFebruary20, 187? application filed January 13, 1877.

To all whom it may concern:

Be it known that I, HARRY HUNT, of Boston, in the county of Suffolk andState of Massachusetts, have invented a new and valuable Improvement inHose-Nozzles; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawing, making-a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawing is a representation of a central verticalsection of my hosenozzle; and Figs. 2, 3, and 4 are detail viewsthereof. it

The object of this invention is to regulate the volume of waterdelivered through a hosenozzle by means of easily adjustable and replaceable devices; also,.to prevent the outflowing stream from beingspattered or broken In the annexed drawing, A designates a taperingtubular hose-nozzle, having a slightly-enlarged tip, a, and an expandedbase, A ofannular shape. At the line where said nozzle begins to taperit is provided with a transverse disk-shaped partition, A (shown in Fig.1,) which has on its rearward or lower side a number of serrations, awhich hold adetachable leather disk, B, to said partition. Two oppositeoblong openings, B B, extend through said disk and partition, as doesalso a central internally screwthreaded perforation, I).

G designates a shell or casing, the rear part of which is internallyscrew-threaded at 0, so as to form part of a hose-coupling, and theforward end of which is formed with a disk, D, adapted to set intoexpanded base A and against leather disk B. Said metal disk D isprovided with a central perforation, d, which corresponds to perforationb, but is not screwthreaded, and with .two opposite oblong openings, DD, which register with openings B B, already described. Said disks areheld more closely together by an annular bead, b, on leather disk B, anda complementary annular groove, 01, on disk D.

E designates a screw'threaded bolt, which passes down throughperforation d, and screws into screw-tapped perforation b, therebyclampi-ng all of together. 7

When a full stream of water is desired, the openings B and D are allowedto fully register.

the above-described parts To lessen the stream, disk D is turned (byturning casing 0) until only a part of each said openings is unclosed.The degree of rotation regulates the decrease of the apertures,

and the consequent diminution of the watersupply.

By turning said casing a sufficient distance, the supply may be entirelyout ofi.

Bolt E clamps the above devices in any desired position of such rotaryadjustment, and whenever a new adjustment is desired, said boltisloosened sufficiently to allow the same.

The employment of leather disk- B protects metal partition A and metaldisk D from being injured by friction, especially during the above;described rotary adjustments. Said disk B is easily removable when worn,and another may easily be substituted for it. In these removable disksany soft material capable of fulfilling the same office may be usedinstead of leather.

It has been found that the stream of water issuing from a hose'nozzle isoften spattered and broken up by the resistance of the inner edges ofthe perforated nozzle-tip. I remedy this defect by slightly enlargingthe tube'of said nozzle A at said tip a, so as to form a mouth, (0(shown in Fig.1.) which allows the air to press upon all sides of theoutflowing stream, keeping it smooth and full, and preserving it frombeing interrupted by the end of said nozzle-tip. 7

What I claimv as new, and desire tosecure by Letters Patent, is

l. The nozzle-tip a, provided with the enlarged month a havingoutwardly-inclined sides 0 c, which are a continuation of the bore ofsaid tip, substantially as described,'and tor the purpose set forth.

2. The combination of nozzle A, having partition A with leather disk B,casing 0, disk D, and clamping screw-bolt E, the above described disksand partitions being provided with oblong registering-openings, arrangedsubstantially as and for the purpose set forth.

In testimony that I claim the aboveI have hereunto subscribed my name inthe presence of two witnesses.

HARRY HUNT.
